San Diego Etsy seller Cutting Boredom makes retrogame-inspired cutting boards shaped like old NES cartridges ("the grooves are able to serve as functional juice grooves"); they're made to order and can feature custom etched messages, Zelda logos and more, though I prefer the plain ones — available in 12"x13" or 9"x10", and in maple, cherry, mahogany and walnut.
